Can You Prove The Big Bang Theory?
7 segments available
Unravel the mysteries of the universe with Nobel laureate John Mather. His groundbreaking work on the COBE satellite, which Stephen Hawking described as one of the most significant discoveries ever, forms the foundation of our understanding of the Big Bang Theory. We explore the universe's intricate beginnings, the significance of pink and blue blobs on a cosmic map, and why gravity's role in creating galaxies and stars is crucial. Get ready for a thought-provoking journey that leaves you with more questions than answers about the mysteries of our vast universe.

Segments Timeline
The Cosmic Map of Pink and Blue
John Mather introduces the significance of the pink and blue blobs on the cosmic map produced by the COBE satellite, which Stephen Hawking hailed as a monumental discovery. He explains how these blobs provide evidence for the Big Bang Theory and the importance of temperature variations in the early universe, which allowed gravity to form galaxies and stars.
"what if I told you that our understanding of The Big Bang Theory and the Very origins of our universe can be traced back to a map of pink and blue blobs the same blurry map that Stephen Hawking descri..."
From Dairy Farm to Nobel Prize
John Mather shares his journey from a dairy farm to becoming a Nobel laureate. He recounts his early fascination with science, sparked by his father's bedtime stories, and his experiences at the Museum of Natural History that ignited his passion for understanding the universe. Mather reflects on how these formative experiences shaped his career in astrophysics.
"also have a three-part series exploring the secrets of space many of which were still uncovering it's part of a longer conversation where I had the pleasure of sitting down with John at the Aspen idea..."
The Birth of the COBE Satellite
Mather discusses the inception of the COBE satellite project during his graduate studies. He recounts the challenges faced with his initial thesis project, which failed, and how that led him to NASA. He describes the successful launch of COBE in 1989 and its groundbreaking measurements of cosmic microwave background radiation, which confirmed the Big Bang Theory.
"[Music] thank you tell us about when you started getting involved I got stressed it down pretty young I think I was about six years old wow I've heard from my dad at bedtime story time that uh living ..."
Revolutionizing Cosmology
Mather explains the revolutionary implications of the COBE satellite's findings, particularly the map of hot and cold spots in the universe. He emphasizes how these variations were crucial for the formation of galaxies and stars, challenging previous notions that divine intervention was necessary for the complexity of the universe.
"job for NASA five years before that we had just landed on the moon for the first time wow okay so okay 1974 I met NASA laboratory in New York City and um okay so NASA puts out this announcement of opp..."
Nature's Complexity and Quantum Mechanics
In this segment, Mather delves into the reasons behind nature's ability to produce complexity. He discusses the roles of quantum mechanics and thermodynamics in shaping the universe, explaining how gravity contributes to the heating and cooling of cosmic material, leading to the formation of stars and galaxies.
"um divine intervention because it's too dang complicated nobody could possibly see how it could work we confuse I don't know how it works yes I don't know how to do it with it can't be done or it's im..."
The Importance of Cosmic Discoveries
Mather reflects on the significance of the pink and blue blobs discovered by COBE, which Stephen Hawking deemed the most important scientific discovery of the century. He discusses the ongoing mysteries of the universe, including the unification of gravity and quantum mechanics, and the implications of dark matter.
"we got from you're saying this image because if this wasn't the case if you're saying gravity didn't exist and create these local changes then what would we see would we instead have seen just a clean..."
The James Webb Space Telescope's Mission
As the senior project scientist for the James Webb Space Telescope, Mather highlights its role in advancing our understanding of the universe. He discusses the unexpected findings regarding galaxy formation and the ongoing mysteries that astronomers are eager to explore, emphasizing the potential for new discoveries in the field of cosmology.
"congratulations what if it weren't true then of course you don't get a prize um but now we have much much more detail to go on let's talk about that right so you were the senior project scientist on t..."
